HP LaserJet Printers Vulnerable to Attacks, Researchers Warn

Millions of Hewlett Packard Co.'s LaserJet printers contain a security weakness that could allow attackers to take control of the systems, steal data from them and issue commands that could cause the devices to overheat and catch fire, according to two researchers from Columbia University.

Printers from other vendors likely have the same issue, leaving users of those devices exposed to similar threats, the researchers said.
